Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine,
More specifically, a game ball is stored in a ball game machine.
Game balls located on the tank member
Equipped with a game ball detection device that detects whether there is more than a certain amount
Related to ball and ball game machines. 2. Description of the Related Art A pachinko machine exemplified as a typical example of a ball and ball game machine is disclosed.
In a dick machine, it is formed in a container shape with an open top on the upper part of the fuselage.
Predetermined prize status on the game board with
Activates the prize ball dispensing device based on the
Configured to pay out the played game balls to the upper and lower ball dishes
You. Above the tank member is a game ball supply device of a game facility
There is a supply duct connected to this supply duct.
Is configured so that the replenishment of the game ball to the tank member is performed.
ing. Here, payment of game balls by the prize ball payout device
The payout is performed according to a predetermined winning state on the game board.
As a result, the number of game balls stored in the tank
Time is not constant. For this reason, pachinko machines have tank members
Detects whether or not the number of game balls stored in the game is equal to or more than a predetermined amount
The game ball detection device (referred to as "prize ball out detection device")
Provided, the number of game balls stored in the tank is less than a predetermined amount.
When the game ball replenishment device prompts you to replenish the game ball
Is configured. As such a game ball detecting device, a
It is arranged to swing freely facing the storage space of the
A rockable displacement that can be performed according to the pressing force from the game ball
Detection for detecting the swing angle position of the bar member and the lever member
And a switch for detecting the swing angle position of the lever member.
By this, the game balls stored in the tank member
Devices for detecting whether or not there is a device are known. [0005] However, as described above,
In a conventional game ball detection device, a push from a stored game ball is used.
A lever member that swings up and down under pressure is located on the tank member side.
The swing angle of this lever member while being pivotally supported
The detection switch that detects the degree position is
It was mounted on the tank mounting part side. For this reason,
When trying to attach the lock member to the tank
Lift the lever member that is about to tilt down
It is necessary to attach the tank member while maintaining the
There is a problem that the work is complicated. Further, in the conventional game ball detecting device, the detection
Small components such as switches are equipped with main mechanisms.
Directly into the main body of the gaming machine, such as
The assembly process of the game machine is complicated
Has become one of the factors that make efficient production difficult
Was. The present invention has been made in view of such a problem.
It is easy to assemble the game ball detection device
Both simplified the main flow of the assembly process
To provide a ball-and-game machine with improved production efficiency
Target. [0008] To achieve the above object, the present invention
The game ball detection device of the invention is provided at the upper part of the game machine,
It is formed in an open-faced container and stores game balls.
Games stored from the exit opening provided on the downstream side of the bottom
A tank member for supplying the sphere and a bottom
It is pivotally supported and stored in the tank member so that it can swing up and down.
Lever part that can be displaced by rocking according to the pressing force from the playing ball
Material and attached to the tank member located below the lever member
Detection switch that detects the tilt angle position of the lever member
And a lever member by a detection switch.
Game ball that detects the rocking angle position of the tank and stores it in the tank member
Is greater than or equal to a predetermined amount. In the above-structured ball game machine, the game ball
A lever member capable of swinging displacement according to the pressing force;
-With a detection switch that detects the tilt angle position of the member
Is integrated with the tank member
Tank member to which the main mechanism of the game ball detection device is assembled
The ball game machine is constructed by attaching
You. That is, the lever member and the detection switch are
Are already connected to each other before the
Is assembled to the tank member in a
Attention to the mutual positional relationship (alignment state) when assembling the body
There is no need to perform assembly work. For this reason, the tank
Pull up and hold the lever member when installing the material
There is no necessity, and the assembling work can be simplified. Also, a portion between the lever member and the detection switch
The assembly work is performed in parallel with the assembly work of the gaming machine body
Can simplify the process of assembling the gaming machine
Efficient production can be performed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described.
